To develop a better understanding of 'in-service' performance of modern marine coatings, this study explored the combined effects of different roughness ranges of foul-release coating (FRC) and light biofouling (slime) on the surface, boundary layer and drag characteristics under a range of 'in-service' conditions. Natural and laboratory biofilms were grown dynamically on FRC panels by exposing panels in facilities dedicated to realistic fouling culture. The boundary layer experiments were conducted in a circulating water tunnel. Boundary layer similarity-law scaling was used to predict the combined effects of coating roughness and biofilms on the added frictional resistance (% Δ C F ) and added required effective power ( % Δ P E ) for a benchmark KRISO container ship (KCS) and a bulk carrier. The increase in % Δ P E due to the presence of biofilms on commercial FRC is estimated to be between 7% and 16% depending on the biofilm type, biofilm thickness and percentage coverage. Significant increases in effective power are estimated for non-fouling control primers with heavy fouling. Moreover, the paper suggests updated roughness allowances ( Δ C F ) for two vessel types assuming FRCs on their hulls with more representative hull roughness ranges and fluffy biofilms.Copaifera pubiflora Benth oleoresin (CPO) is used as an anti-inflammatory, wound healing, and antimicrobial. This paper reports the cytotoxic, anti-inflammatory, and antinociceptive activities of CPO. CPO (10?mg/kg) did not affect locomotor capacity in the open-field and rotarod tests and was not cytotoxic to CHO-k1, THP-1, and L929 cell lines. It was active in the formalin test at 3?mg/kg by 86?±?3% and 96?±?3%, respectively, for the first and second phases. At 10?mg/kg, CPO inhibited 90?±?7%, the pain in the mechanical hyperalgesia test. In the tail-flick test, CPO at 3?mg/kg affected the tail-flick latencies in mice by 77?±?20%, which in combination with naloxone was only partially reduced. At 3?mg/kg CPO inhibited 80?±?12% the carrageenan-induced paw edema, and at 3?mg/kg it reduced by 91?±?5% the nociception on acetic acid-induced abdominal writhing. Therefore, CPO possesses anti-inflammatory and antinociceptive activities.The interface between the patient and the health service has changed, which constitutes a potential problem for various policy-makers. Using a critical policy perspective and drawing on the theory of problem framing, this paper explores how actor groups with different responsibilities perceive the patient as a constructed policy problem. This is a qualitative study where data consists of single episode interviews with healthcare politicians, senior administrators, service strategists, and unit mangers from one regional health authority in Sweden. A thematic content analysis of the interviews was carried out in accordance with "the framework approach". The study illustrates how the actors interpret their reality using diverse problem frames. This becomes more visible when the framing is disentangled with regard to what perspective they employ in relation to different accounts society or the individual, or the (healthcare) system or the (healthcare) professional. The actor groups are part of the same institutional context, which explains certain tendencies of similarities in terms of the accounts being used, but still they approach the constructed problem differently which is visible as shifts-scaling up and down-between different accounts. By analyzing and structuring the various problem frames (including its policy styles) we can enhance our knowledge about how those responsible for the governance of healthcare approach the patient as a policy problem, as something that concerns only the patient and/or the provider, or as something that needs to be addressed in broader strategic terms.Assessing the risk perception of workers can be very informative in predicting their behavioral outcomes, including task and contextual performance. Yet, research to assess the effect of risk perception on task performance and contextual performance remains scarce. Thus, this study explored the effect of risk perception of work-related musculoskeletal disorders on task and contextual performance in nurses. This study further examined safety behavior as a mediator of these relationships. Using structural equation modeling, the researchers examined these relationships by employing a cross-sectional survey with a quantitative approach. The data was collected via questionnaires from 382 nurses who work in three major hospitals in Accra Metropolis, Ghana. The results showed that nurses' risk perception positively influenced their task and contextual performance, and that safety behavior partially mediated the effects of risk perception on task and contextual performance. This study offers a theoretical framework and empirical evidence for the concept of risk perception and its association with safety behavior, task, and contextual performance. To the best of our knowledge, this is the first study to assess the relationships that exist among these variables. Thus, future studies are needed to verify the causality of the relationships.Waka ama is unique as a sport because, as well as the physical benefits for paddlers, it also creates opportunities for participants to experience and connect with the natural environment. This research draws on interviews with waka ama paddlers in Aotearoa New Zealand to illustrate how the well-being of the environment connects to the spiritual, cultural, and physical health of people. Results highlight the multifaceted benefits of participating in waka ama. As well as the physical benefits for paddlers, waka ama also has a strong tikanga, which encourages language revitalization with the use of te reo Māori through karakia, waiata, and the general terms used associated with waka. It also creates opportunities for participants to experience and connect with the natural environment and improve their health. https://www.selleckchem.com/products/pentetic-acid.html The knowledge gained from participants provide evidence of effective ways to improve health and well-being within communities with a particular focus on waiora, the spiritual connection between hauora and the environment.
